ADTRAN is joining the G.722 HD voice crowd - really.

Without going into details, sources, or forward-looking statements, ADTRAN is in the process of testing its G.722 wideband firmware upgrade for its handsets. A formal introduction/release of the firmware is expected “within six months,” according to one account.

ADTRAN’s IP phones were engineered from the start to support G.722, with the company planning to issue a firmware release for the codec upon “customer demand.” Followers of the company shouldn’t be surprised at its relatively conservative approach to business.
